The IPCC claimed that the Little Ice Age was just in the Northern Hemisphere. This research call that bit of factless story telling into question. The LIA was global.
The U.S. has a research station located at the WAIS divide where scientists associated with the Scripps Institution of Oceanography conducted an analysis to determine the Little Ice Age impact on the southern polar region.
“The authors (Orsi et al.) write that “the Northern Hemisphere experienced a widespread cooling from about 1400 to 1850 C.E., often referred to as the Little Ice Age (hereafter LIA),” which they describe as “the latest of a series of centennial scale oscillations in the climate,”…three researchers, all from the Scripps Institution of Oceanography, report determining that “the WAIS Divide was colder than the last 1000-year average from 1300 to 1800 C.E.,” and they say that “the temperature in the time period 1400-1800 C.E.” – which meshes well with the chronology of the LIA in the Northern Hemisphere – “was on average 0.52 ± 0.28°C colder than the last 100-year average.”…stating that their result “is consistent with the idea that the LIA was a global event, probably caused by a change in solar and volcanic forcing…” [Anais J.
